Freesia is a genus of herbaceous perennial flowering crops in the family Iridaceae, first described as a genus in 1866 by Chr. Fr. Echlon (1795-1868) and named after German botanist and doctor Friedrich Freese (1794-1878). It is native to the eastern side of southern Africa, from Kenya south to South Africa, most types being within Cape Provinces. Kinds of the past genus Anomatheca are actually included in Freesia. The plant life often called "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of lots of Freesia types. Some other species are also grown up as ornamental plant life.
They are simply herbaceous vegetation which increase from a conical corm 1-2.5 cm diameter, which sends up a tuft of slim leaves 10-30 cm long, and a sparsely branched stem 10-40 cm high bearing a few leaves and a loose one-sided spike of blossoms with six tepals. Many varieties have fragrant narrowly funnel-shaped bouquets, although those previously placed in the genus Anomatheca, such as F. laxa, have even flowers. Freesias are being used as food plants by the larvae of some Lepidoptera kinds including Large Yellowish Underwing.
CULTIVATION AND USES
The vegetation usually called "freesias" derive from crosses made in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these kinds and the pink- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have blossoms ranging from white to yellowish, red, red and blue-mauve. These are mostly cultivated appropriately in the Netherlands by about 80 growers.[3] Freesias can be quickly increased from seed. Due to their specific and satisfying scent, they are generally used in side products, shampoos, candles, etc.[citation needed], however, the flowers are mainly used in wedding bouquets. They can be planted in the street to redemption in USDA Hardiness Areas 9-10 (i.e. where the temperature will not show up below about -7 ?C (20 ?F)), and in the spring in Zones 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other varieties of the genus which is often cultivated. Smaller than the scented freesia cultivars, it includes flat somewhat than cup-shaped blooms. Extensive 'forcing' of this bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary methods to satisfy chilly dormancy which results in creation of buds in just a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plant life (in botanical use frequently simply herbal products) are plant life which may have no persistent woody stem above earth. Herbaceous vegetation may be annuals, biennials or perennials. Annual herbaceous plants pass away completely by the end of the growing season or when they have got flowered and fruited, plus they then develop again from seed. Herbaceous perennial and biennial vegetation may have stems that pass away by the end of the growing season, but parts of the plant make it through under or near to the bottom from season to season (for biennials, until the next growing season, when they blossom and perish). New development produces from living tissues remaining on or under the ground, including roots, a caudex (a thickened portion of the stem at walk out) or numerous kinds of underground stems, such as bulbs, corms, stolons, rhizomes and tubers. Examples of herbaceous biennials include carrot, parsnip and common ragwort; herbaceous perennials include potato, peony, hosta, mint, most ferns & most grasses. In comparison, non-herbaceous perennial crops are woody plants that have stems above floor that stay alive through the dormant season and develop shoots another season from the above-ground parts - included in these are trees, shrubs and vines.
